for storing energy
The human body deals with excess glucose by turning it into glycogen, fatty acids, triglycerides, or energy.
Our bodies cannot store excess protein once it is consumed, so the excess amino acids are converted to carbon skeletons that are turned into glucose or fat and then stored as fat or metabolized for energy needs. **stored as glycogen & fat** jmata~
Excess amino acids cannot be stored in the body because unlike fats and carbohydrates, there is no specialized storage form for amino acids. Instead, the body must convert them into energy, store them as fat, or excrete them through the urine. Thus, any surplus amino acids are not efficiently retained in the body.
I had the same question and saw no answers posted. In a hope to begin a thread, here is my guess. Osmolarity. The same reason why excess glucose molecules are stored as glycogen. Similarly, excess fatty acids are tucked away as TAG. It seems quite problematic to put excess AA into proteins in a random fashion, because this will surely lead to insoluble protein aggregates or soluble proteins with unwanted functions.
No, not all fatty acids can be synthesized by the body. The body is not capable of synthesizing polyunsaturated or trans fatty acids.
There are two main types of fatty acids found in the human body: saturated fatty acids and unsaturated fatty acids. Unsaturated fatty acids can be further classified into monounsaturated and polyunsaturated fatty acids.
When the body has an excess of protein that it doesn't need for energy or building muscle, it can convert the excess protein into fat through a process called deamination. During deamination, the body removes the nitrogen from the protein molecules and converts the remaining carbon and hydrogen into fatty acids, which are then stored as fat in the body.
Fatty acids are converted into acetyl-CoA through beta-oxidation in the liver before being further metabolized to produce energy. Since they are broken down and utilized for energy production, fatty acids are not typically excreted in urine. Instead, any excess fatty acids are stored as triglycerides in adipose tissue for later use.
Lipids are broken down into fatty acids and glycerol during digestion. The fatty acids and glycerol are then absorbed into the bloodstream and used as energy sources by the body or stored for later use.
The fats stored in your body consist mostly of triglycerides, which are made up of three fatty acid molecules attached to a glycerol molecule. Triglycerides are the main form of fat stored in adipose tissue for energy storage and insulation.
When you eat more carbohydrates than your body needs for energy, the excess carbohydrates are converted into fat through a process called de novo lipogenesis. This occurs mainly in the liver, where the excess carbohydrates are converted into fatty acids and then stored as fat in adipose tissue for later use.
When at rest, the body's fuel source is primarily fatty acids derived from stored fats. These fatty acids are broken down through a process called lipolysis to provide energy for basic bodily functions.
