Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
In the gut, amino acids are absorbed from the small intestine into the blood by active transport. However, if you are referring to amino acids being reabsorbed in the kidney from the nephron back to the blood, then that is incorrect - amino acids aren't reabsorbed at all, because they weren't filtered in the first place. This is due to the protein molecules being too large to diffuse across the Bowman's Capsule.
Amino acids held together by peptide bonds.
Hemoglobin is a protein found in red blood cells that transports oxygen. It is composed of four protein subunits, each containing amino acids. Therefore, hemoglobin does contain amino acids as they are the building blocks of proteins.
One common method to separate amino acids from fatty acids is through chromatography. Amino acids are more polar and can be separated based on their different affinities for the stationary phase, while fatty acids can be eluted separately due to their differing solubilities. Another method could involve precipitation using different solvents where amino acids and fatty acids can be separated based on their solubilities in the respective solvents.

tRNA. Transport ribonucleic acid, it is a 3 loop structure that brings specific amino acids to the ribosome. Has anticodons specific to the codons.

Proteins are made up of monomers called amino acids.

Carrier proteins facilitate the movement of amino acids across the cell membrane through facilitated diffusion, which does not require energy input. This process relies on the concentration gradient of amino acids across the membrane.
