When fatty acids cannot pack together tightly enough to make a solid fat they have a?
very litte glycerol
What else can I help you with?
Why are unsaturated fatty acids better than saturated fats for letting substances in and out of the cell?
Unsaturated fatty acids have double bonds in their carbon chains, which create kinks and prevent the fatty acids from packing tightly together. This increases the fluidity of the cell membrane, allowing substances to move more easily in and out of the cell. In contrast, saturated fats lack double bonds and pack tightly together, resulting in a more rigid membrane that is less permeable to substances.
What can acids and bases do alone or together?
bases neutralise the acids
What structure in the membrane causes plasma membranes to resist freezing?
The presence of unsaturated fatty acids in lipid bilayers helps plasma membranes resist freezing by preventing the lipid molecules from packing tightly together. Unsaturated fatty acids create kinks in the lipid tails, increasing membrane fluidity and allowing the membrane to remain flexible at lower temperatures.
Where amino acids are strung together to form a protein?
Amino acids are bonded together with peptide bonds in protein synthesis at the ribosomes.
Molecules that bond together to produce a protein is what?
Amino acids are the molecules that bond together to produce a protein. Proteins are made up of chains of amino acids that are linked together through peptide bonds. The sequence of amino acids in a protein determines its unique structure and function.
Why do saturated fatty acids have structures while unsaturated fatty acids have bent structures?
Because unsaturated fatty acids have many double bonds and the atoms cannot rotate freely around those double bonds. In the saturated fatty acids, there are no double bonds (only single bonds) and so the atoms are free to rotate.
What are the structural differences between saturated and unsaturated fatty acids?
Saturated fatty acids have single bonds between carbon atoms, making them straight and able to pack tightly together. Unsaturated fatty acids have at least one double bond, causing a kink in the chain and preventing tight packing.
Why are unsaturated fatty acids better than saturated fats for letting substances in and out of the cell?
Unsaturated fatty acids have double bonds in their carbon chains, which create kinks and prevent the fatty acids from packing tightly together. This increases the fluidity of the cell membrane, allowing substances to move more easily in and out of the cell. In contrast, saturated fats lack double bonds and pack tightly together, resulting in a more rigid membrane that is less permeable to substances.
What is a Fatty acids that can be kinked and is liquid at room temp?
Unsaturated fatty acids, such as oleic acid (found in olive oil), can have kinks in their carbon chains due to the presence of double bonds. This kink prevents the molecules from packing tightly together, keeping them in a liquid state at room temperature.
What can acids and bases do alone or together?
bases neutralise the acids
Which cannot be formed by fatty acids?
Nucleic acids cannot be formed by fatty acids. Nucleic acids, such as DNA and RNA, are composed of nucleotides, whereas fatty acids are molecules that primarily serve as a source of energy and as building blocks for cell membranes.
What molecule links together to form proteins?
Amino acids
Can essential amino acids be made from glucose?
can the essential amino acids be made from glucose
What is the term for the nine acids that the body cannot manufacture?
essential
What structure in the membrane causes plasma membranes to resist freezing?
The presence of unsaturated fatty acids in lipid bilayers helps plasma membranes resist freezing by preventing the lipid molecules from packing tightly together. Unsaturated fatty acids create kinks in the lipid tails, increasing membrane fluidity and allowing the membrane to remain flexible at lower temperatures.
What type of bonds appear in unsaturated fatty acids?
In unsaturated fatty acids, double bonds appear between carbon atoms. These double bonds create kinks in the carbon chain, which disrupts the ability of the molecules to pack tightly together. This is why unsaturated fats are typically liquid at room temperature.
Where amino acids are strung together to form a protein?
Amino acids are bonded together with peptide bonds in protein synthesis at the ribosomes.
