You are probably referring to rough endoplasmic reticulum or ribosomes.
Ribosomes
Ribosomes are the site of Protein synthesis
Ribosomes
Ribosomes are the structure that synthesize proteins. They are located on the endoplasmic reticulum, which is an organelle inside the cell.
The right question would be, "Do cells make proteins FROM small structures called amino acids?" The short answer is, yes. If your interested in how look up the Hierarchy of Protein Structures. Specifically: Primary Structure ie. the amino acid sequence Secondary Structure ie repeating folding patterns (which help determine function.) Tertiary Structure ie. many folds and patters create a 3-D shape. For some proteins this is the final structure to a functional protein (such as ribonuclease). Quaternary Structure ie. Most functional proteins are comprised of two or more polypeptides that each adopt a Tertiary Structure (see above) and then assemble with each other. When proteins consist of more than one polypeptide chain, they are said to have Quarternary Structure.
DNA is packaged very tight by proteins. Proteins found around the DNA supports both the structure and functions. The proteins and the DNA make up the chromosomes. Proteins and DNA in animal cells are chromatin! DNA contains information because of the DNA's structure!
There is not something known called primary proteins. But proteins do have primary structure. Poly peptide chains after synthesized from ribosomes make up primary structure of a protein. this will afterward form 2D and 3D structure with additional structures and interactions.
ribosomes
ribosomes
Proteins are produced as polymer of amino acid chains. They gain secondary structure elements such as alpha helix, beta sheet during folding and for their three dimensional structure. Some proteins such as Hemoglobin make quaternary structure where they form the final structure with four different subunits of two different proteins interacting each other.
phospholipid and cholesterol
Amino Acids are small monomers of proteins that make protein up.
Yes it does.
