1 pts
which lipid acts as a \tissue hormone\?
triglyceride
prostaglandin
steroid
phospholipid
question 17
1 pts
the basic building blocks of fats are:
monosaccharides.
disaccharides.
amino acids.
fatty acids and glycerol.
question 18
1 pts
which level of protein structure refers to the number, kind, and sequence of amino acids?
primary
secondary
tertiary
quaternary

Explanation:

• Question 16: Prostaglandins are known as "tissue hormones" as they act locally at the site of production. They have various physiological functions like regulating inflammation, blood - clotting, and smooth - muscle contraction.
• Question 17: Fats are esters of fatty acids and glycerol. Fatty acids and glycerol are the basic building blocks of fats. Monosaccharides and disaccharides are related to carbohydrates, and amino acids are the building blocks of proteins.
• Question 18: The primary structure of a protein is defined by the number, kind, and sequence of amino acids. Secondary structure involves local folding patterns like alpha - helices and beta - sheets, tertiary structure is the overall 3 - D shape, and quaternary structure is related to the arrangement of multiple polypeptide chains.

Answer:

Question 16: B. Prostaglandin
Question 17: D. fatty acids and glycerol
Question 18: A. Primary
