Biochemistry is the study of the actions of the main metabolic processes of living organisms, which are protein synthesis (DNA and RNA molecules, genetic codes and how they work, enzyme formation and function, etc), glycolysis (cellular respiration, aka the Krebs cycle/citric acid cycle to break down glucose molecules to release chemical energy and oxydative phosphorylation, the use of that chemical energy to form ATP molecules in which the chemical energy is put in a form the cell can use, and lipid chemistry (the study of the pathways in which fatty acids are formed into lipids and fat molecules and cholestrol formation and function).
Essentially, biochemistry covers the chemical reactions necessary for cellular and organism metabolism
The RDA for protein is 0.8 g per kilogram of body weight. This man's weight is 190 lb, or 86 kg; 86 kg × 0.8 = 69.1 g protein per day. Thus, an intake of 150 g is more than twice his RDA of 69.1 g of protein per day.
Recommended Dietary Allowance (RDA) of protein for adults is 0.8 g per kilogram of body weight. To determine your RDA for protein, multiply your weight in pounds by 0.36.The protein RDA for adults is 0.8 grams per kilogram of healthy body weight per day.
Proteins build muscle mass and contour, facilitate hair, nails and bone growth, regulate energy levels, and support chemical processes within the body which include enzyme, hormone and antibody production.
